I do have an opinion like everyone else. But, I'm conflicted. The TRX changes how ford may play the release of next raptor. There has been really no competition to the raptor - and the gen 1 to gen 2 took a long time because it was an all new F150 - the move to the aluminum body was a big jump in terms of tooling etc. Made sense that the gen 2 raptor came 3 years after the last gen 1. Assuming the same frame is used from the current f150 to the 2021 that would make things a bit easier for the raptor since the raptor's frame is reworked a bit to be stronger in spots.
Part of me says ford has a lot on their plate with the new f150 and the bronco and that the raptor will wait a couple of years, just like the all electric f150. The other side, now with the TRX in play, Ford might not want there to be a void in the market for Fiat to potentially fill depending on how good or ****** they roll out and present the TRX. As mentioned, the 3 year gap between gen1 and gen2 is a trend, not set in stone. If I had to guess though, I'd say that there will NOT be a 2021 Raptor and that maybe Ford will roll with a 2022 Raptor to be released summer of 2021.
